Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

GRK2-mediated receptor phosphorylation and Mdm2-mediated ?-arrestin2 ubiquitination drive clathrin-mediated endocytosis of G protein-coupled receptors.

Zhang X, Zheng M, Kim KM

Clathrin-mediated and caveolar endocytic pathways represent the major routes through which G protein-coupled receptors (GPCRs) could be internalized. GPCR kinase 2 (GRK2) and ?-arrestins are representative proteins that mediate the GPCR endocytosis. However, the molecular mechanisms through which GRK2 and ?-arrestin mediate clathrin-mediated and caveolar endocytosis remain unclear. In this study, we determined the cellular components and processes that mediate ... [more]

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.
